Handheld gas detectors are portable devices used to detect and measure the level of various gases in the air. These detectors are widely used in industries such as food processing, agriculture, and mining to ensure worker safety and prevent hazardous gas exposure. In the food industry, gas detectors can also be used to measure emitted gases in food to ensure their quality and safety.
Why Measure Emitted Gas in Food?
The quality and safety of food are major concerns in the food industry. Emitted gases in food can be used as indicators of poor quality, contamination, or spoilage. Additionally, some gases produced during the manufacturing or packaging process could negatively impact the taste, texture, and shelf-life of food products. As a result, it is important to monitor the emitted gases in food to mitigate these risks.
Which Gases are Measured?
Different gases can be measured using handheld gas detectors, depending on the specific needs of the food industry. Some common gases measured in food include:
1. Carbon dioxide (CO2) – This gas is produced during the natural decay of organic matter. CO2 levels in food can provide important information on its freshness, ripeness, and shelf-life.
2. Oxygen (O2) – O2 levels can be used to determine the quality and freshness of food. As the oxygen content decreases, the food’s quality and shelf-life also decrease.
3. Ammonia (NH3) – This gas is produced by bacteria during the decomposition of protein. High levels of NH3 in food can indicate spoilage or contamination.
How are Gases Measured in Food?
Handheld gas detectors rely on various technologies to detect and measure the level of gases in food. Some of these methods include electrochemical, infrared, and catalytic sensors. Electrochemical sensors are commonly used for measuring CO2 and NH3, while infrared sensors are used for measuring CO2 and O2. Catalytic sensors are typically used for detecting combustible gases, such as methane, which can be produced during food processing.
In conclusion, handheld gas detectors are an essential tool for measuring emitted gases in food. These detectors can provide important information on the quality, freshness, and safety of food products. By monitoring emitted gases, food manufacturers and processors can ensure that their products meet the highest standards of quality and safety.
